AGITATUR FOR WASHING MACHINES.

Application riled July 1 l,

This invention relates to agitators tor washing machines.

Une of the objects of the invention is in the provision of an agitatingdisk for wash" 5 machines fashioned with a plurality cl comparativelywidely spaced blade H1631" bers'that merge with a centrally disposedpost rising from the disk, there being also provided snialler ribsdisposed intermediate th ater agitating blades, said ribs operatin tointercept the returning water our re ts initially set up by the blademembers, and also acting as an additional clothes agielement,

Another object is in the provision or specially formed agitator memberfor washmachines, wherein a dish member. hava centrally disposed postmember or .lrivinp; ,coni'iection has radially extending l nm aplurality of unusually "idely n as sei'iarated writer agitating blades,as well iller ribs, of smaller radius, disposed inlei-mediate the wateragitating blades, said ribs being; iashioned in a manner to interceptthe returning water current set up by agitating blades and to agitatethe clothes portions carried by said currents, with resultant increasinge iciency of the washoperation.

.i'h. turther object lies in the provision ot a specially formedagitating dish for washing machines comprising a centrally disposed porthaving, a plurality of comparatively widely spaced water agitatingblades radially extending therefrom, and intermediate web portionsdisposed intermediate the agitater blades, said web portions being angurlarly shaped to provide a substantial agitate surface between the blademembers, the er edges of said. web portions diminish towards their upperends until they finally merge with the post member.

@ther objects will appear in the following' specification, taken inconnection with the annexed drawings, in which- 1 is perspective view ofthe special ly formed agitator member, the upper por-- tion of which iscut away tor a more do tailed view oil the driving connection thereforReferring to the drawings, there is shown merely a single figureillustrating the present special agitator member for washing machines.lln view of the fact that this agitator is adapted for use in a type of1926.

being a driving connection through the bottoin center or the tub, saiddriving connection being elevated to a point above the normal waterlevel in the tub, the special dish member shown herein attached theretoin a manner now to be described The vertically disposed drive shaft,betore mentioned, is shown at 10, and has a surrounding supporting;column ll, securely attached in a manner not shown, to the bot torn ofthe tub and supporting brackets therefor. A lap; 12 is securelylast-erred as at 13 to the upperend ,of the drive sha "t lO,'and thespecial agitator member has the interior portion of the upper end itlash ioned in a manner to conform to the shape or the lug 12, wherebysaid agitator may be lifted therefrom by simple vertical lilt, saidconnection, however, being of a fixed nature and providing the drivingconnection be tween the drive shattand the agitator, Us cillation ot thedrive shaft 10 and conse quently the agitator member, is effectedthrough any type of gear mechanism, not shown. 'llhev agitator itselt'comprises an oscillating disk 15, there being centrally disposed thereonand rising therefrom, a center post 16, the same providing the con--necting Ineans bet-ore described,, with the drive shaft, Three wateragitating blade members 17 extend radiall from the center post 16, Theseagitatcrb adesextend to a point substantially adjacent the periphery otthe disk 15, and provide the main water agitating elements, the movementof said blades against the water in the tub acting to throw the water,due to centrifugal force, against the sides of the tub, By utilizingonly three water agitatingblades, it has been found that a greaterdegree of water agitation results than by utilizing a larger numb-er,and hence in using only three blades, they maybe disposed atcomparatively widely spaced points.

Disposed intermediate the water agitating blades 17 are radiallyextending ribs or web portions 18, projecting, at their lower ends, asat 19 a substantial distance radially upon the disk 15. The outer edges20, however,

incline upwardly towards the axis of post 16, with the result thatsubstantially all of the agitating surface of said ribs liesintermediate the widely spaced'agitator blades 17.

Applicant is aware that various water agitating disks have beenheretofore used, of many sizes, shapes and arrangement of blade members.It has been found, however,

that the use of merely a plurality of water agitating blades as 17,without the intermediate rib or web portions, results in such violentaction upon the clothes washed, as in some instances to damage same.After exhaustive tests and experiment, applicant has found that bydisposing the specially formed rib members 18 between the comparativelywidely spaced agitator blades, the returning watercurrents initially setup by the agitator blades 17, were intercepted by said ribs 18, tofurther increase said water agitation by giving same a sort of rollingeflect, which had a tendency to turn the clothes over and hence increasethe eficiency of the washing operation. v

Due to the comparatively widely vspaced blade members, and the nature ofthe water currents set up thereby, the displaced water.

cepted, with an increased clothes agitating my It will be noted that theribs 18 have substantially all their agitating surface located at apoint below and between the widely spaced blade members, at which pointsthe returning water currents initially set up by the agitator blades areintercepted.

What I claim is:

1. An agitator for washing machines, comprising a plane, a horizontallydisposed disk, a vertical post rising from the center of said disk, aplurality of radial blades extending from the lower portion of said postand terminating adjacent the circumferenceof said disk, radial agitatingribs merging with said post and terminating a substantial distancebeyond the circumference of the post, the outer edges of said ribsinclining upwardly toward the axis of said post. p

2. An agitator for washing machines, comprising an oscillating diskhaving a central post rising therefrom, comparatively widely spacedblade members extending radially from said post to a point substantiallyadjacent the periphery of said disk, and smaller rib members mergingwith the central post and extending radially a short distance on thedisk, said rib members being disposed intermediate the blade members.

In testimony whereof it have hereunto affixed my signature;
